CONCLUSION: The changes in brain tissue impedance before and after ischemia can be imaged and it could be used as a variable for EIT imaging.
结论：缺血前后脑组织阻抗变化率满足成像要求，可以将其作为一个成像变量。

Longitudinal vibration of pile with variableimpedance (variable sections or modulus) in layered soil undergoing arbitrary load is theoretically investigated.
对成层土中变阻抗(变模量或变截面)桩在任意激振力作用下的纵向振动特性进行了研究。

Still further, a controller may be coupled to receive a control signalcorresponding to a variableimpedance level, and control a local oscillator coupled to the mixer responsive to the control signal.
